I have to reformat my hard drive and reinstall all of my programs. What do I do about Creative Cloud? I also still need access to CS6 (I have a Marksware converter for InDesign to Quark).

This is a MacBook Pro 15" (Model number A1286) running Mavericks. Hard drive is fine but system software has been corrupted. I cannot simply restore from Time Machine as it will copy the corrupt system.

Will I have to find all of my serial numbers before I can launch any of the programs?
